FMS6400-1 Dual-Channel Video Driver

The FMS6400-1 is a dual Y/C 5th-order Butterworth lowpass video filter optimized for minimum overshoot and flat group delay. The device contains a summing circuit to generate filtered composite video. In a typical application, the Y and C input signals from DACs are AC coupled into the filters. Both channels have DCrestore circuitry to clamp the DC input lev.
